Pin Description
Pin Number
1
Pin Name
/MR1
Pin Function
Digital Input; supervisor 1. Driving this pin low initiates an immediate and
unconditional reset. If VCC1 is above the threshold when /MR1 is released
(returns high), RESET1 will be de-asserted no less than t
RESET1
later. /MR1 may
be driven by a CMOS or TTL logic signal or a mechanical switch. De-bouncing
is performed internally. /MR1 has an internal pull-up to VCC1; leave open if
unused.
Ground return for supervisor 1.
Digital Input; supervisor 2. Driving this pin low initiates an immediate and
unconditional reset. If VCC2 is above the threshold when /MR2 is released
(returns high), the /RESET2 will be de-asserted no less than t
RESET2
later. /MR2
may be driven by a CMOS or TTL logic signal or a mechanical switch. De-
bouncing is performed internally. /MR2 has an internal pull-up to VCC2; leave
open if unused.
Ground return for supervisor 2.
Digital Output; open-drain; supervisor 2. Asserted low whenever VCC2 falls
below the threshold voltage. It remains asserted for no less than t
RESET2
and is
de-asserted after VCC2 returns above the threshold.
Analog Input. Power supply input for supervisor 2.
Digital Output; open-drain; supervisor 1. Asserted low whenever VCC1 falls
below the threshold voltage. It remains asserted for no less than t
RESET1
and is
de-asserted after VCC1 returns above the threshold.
Analog Input. Power supply input for supervisor 1.
